Description
Technical field
The utility model relates to a kind of CNC milling machine, relates in particular to a kind of CNC milling machine lifting platform part feed transmission structure.
Background technology
The structure of numerical control column and knee type CNC milling machine lifting platform feeding transmission place of lathe is at present: drive bevel-gear sett by servomotor, by bevel gear power is reached synchronous pulley again, driving elevating screw by synchronous pulley rotates, and then drive lifting platform vertical feed, add self-locking device on the bevel gear, prevent to glide automatically because of the lifting platform that ball-screw can not self-locking brings, but this wherein also has its unsafe factor, if synchronously band aging with age or other or the like the reason fracture, then self-locking device will no longer play any effect, lifting platform thereby downslide automatically cause unpredictable danger; This wherein only has a pair of gear drive, and a pair of synchronous band transmission is with transmission to increase to turn round effect too little synchronously, is not enough to satisfy users' demand.
Summary of the invention
The purpose of this utility model provides a kind of safe and reliable and transmission and increases and turn round the big CNC milling machine lifting platform part feed transmission structure of effect.
For achieving the above object, the technical solution adopted in the utility model is: a kind of CNC milling machine lifting platform part feed transmission structure, comprise that side hangs over the reduction gear box on lifting platform right side and the servomotor of band dead electricity band-type brake device, it is characterized in that: the output tensioner of the servomotor of band dead electricity band-type brake device connects the horizontal bevel gear that is positioned at reduction gear box, laterally the bevel gear tooth connects vertical bevel gear, vertically the bevel gear key is connected on the final drive shaft, vertically bevel gear is positioned at the bottom of final drive shaft, the top key of final drive shaft is connected with travelling gear, the right side design of final drive shaft has counter drive shaft, the top key of counter drive shaft is connected with travelling gear, final drive shaft is connected by travelling gear with counter drive shaft, the top key of counter drive shaft is connected with the auxiliary driving gear, the auxiliary driving gear connects the ball-screw gear, connect ball screw assembly, on the ball-screw gear, the ball-screw gear is positioned at the top of ball screw assembly.
In this structure, reduction gear box is vertical mutually with the servomotor of band dead electricity band-type brake device.
In this structure, the servomotor of reduction gear box and band dead electricity band-type brake device is parallel to each other.
The utility model has the advantages of and be: because the utility model uses all-gear drive to slow down, increase and turn round, increase that to turn round effect big, the feeding of safe and reliable realization numerical control column and knee type CNC milling machine lifting platform, when not feeding of lifting platform, because the servomotor from lifting platform to band dead electricity band-type brake device all is rigid gear drive, and servomotor band dead electricity band-type brake device, can prevent effectively because of not self-locking of ball-screw, the danger that lifting platform is conducted oneself with dignity and glided and bring is so use the utility model effective.
